Question.

No.
Im still learning about engines and cars.
That means that i dont know how to do that.
I never got engine failures with mij MR2 so i never tryed a thing like that.
But some explaining would be nice.
Bring it on.

It is not a sensor - it's an actuator.

It opens to allow more air when you turn on lights or similar device in order to compensate the load on the alternator and the RPM drop.

How can i make this actuator work all the time? I need some more rpm when idle... :wink:

1. Bypass it

2. Connect one of the tapped openings on the trottle body to the other opening on the filter box. Even better - you can add manually controlled VISV - from a junkyard toyota. just take it with the connector and install it. It may look a little bit different if newer model but the function is the same.

Bluetop has two VISVs - one on the filter and one controlling the TVIS.
Redtop Small port also has two - one on the filter and one controlling the fiel pressure regulator.

I have no filter box ... I use a Sparco filter instead...
So what am i supposed to do to by-pass it?

You can take air from the tube before the trottle body and connect it to one small vacuum openings on the TB.

If you show me a photo maybe i can give you some ideas.
